  Back in '83 Moto sold a part called MC6839 "Floating Point ROM" for
the 6809.  It is an 8K ROM with code supporting the IEEE STD draft 8.0.
It has the following formats: single, double, & extended. It has the
following operations: add, subtract, multiply, divide, sqr rt,
remainder, integer part, abs val, neg, int->fp, fp->decimal string,
predicate compares, and condition code compares. It has 4 rounding
modes, 2 closure modes, and a normalize mode.
  I believe I have one in my spares box.
